How do I implement middleware in ASP.NET Core for order processing?

To implement middleware in ASP.NET Core for order processing, you can create a custom middleware class that handles requests and responses.

What should I include in my middleware to handle order validation?

You should include logic to check the order details, such as item availability and payment status, before proceeding.

Can you show me a code example of such middleware?

Sure! Here's a simple example:

public class OrderMiddleware {
    private readonly RequestDelegate _next;

    public OrderMiddleware(RequestDelegate next) {
        _next = next;
    }

    public async Task InvokeAsync(HttpContext context) {
        // Validate order here
        await _next(context);
    }
}

Don't forget to register it in the Startup class!

How do I register this middleware in the Startup class?

You can register it in the Configure method like this:

public void Configure(IApplicationBuilder app) {
    app.UseMiddleware<OrderMiddleware>();
    // other middlewares
}
